When running, where do you start and run fast?

Sprint: Many people think that the squat start is the fastest, because there are rules in international competitions. However, for ordinary students or junior athletes, the squat start is not dominant. Because of the squat start, the center of gravity of the body gradually rises after the start, and you can also find it in high-level competitions. But this requires long-term professional training and a certain physical quality. I used to be in a sports school. Usually, when testing the results in training, the players basically start with a standing start, but the results will be better. The standing start we use is not the same as the ordinary standing start in primary school. When preparing for the start, we stand back and forth with our feet, with our center of gravity on our front feet and our back feet ready to push the ground. Legs slightly bent, pursed, hehe, the cat is covered by the waist, the body leans forward slightly, and the arms naturally droop. When preparing for the start, the center of gravity slowly leans forward. Don't lift your body in the first half. Raising your center of gravity too fast will affect the starting speed. It's verbose, hehe, imagine the action yourself first. I think this startup method is quite effective.

Long-distance running: Just stand, there's nothing to ask. ....
